Home » News and Events » Gas Permeable Lenses: Do They Make Sense for You?


While you may be most familiar with soft contact lenses, another less familiar type of contact lens materials exists: rigid gas permeable (RGP) lenses, also known as oxygen permeable lenses.

In reality, RGP lenses involve more modern technology than soft lenses, which are longer-lasting, can be more effective in improving eyesight, and offer increased durability and resistance to protein deposits. Additionally RGP lenses may also be cheaper in the long term than soft lenses. Certainly, you need to first consult with an eye doctor to decide if GPs suit your needs. Our optometry staff can assist you in ascertaining whether you’re a candidate for hard lenses.

Since an RGP is constructed from inflexible material, it does a good job of maintaining its shape when you blink, which tends to afford crisper vision than the typical soft lens. Additionally RGPs are especially durable. Though they can crack if stepped on, they don’t tear easily like soft lenses. Also, since they consist of materials that don't include water, proteins or lipids from your tears won't stick to GPs as readily as they will to soft lenses. Those of you who are especially particular about vision quality will most likely opt for RGPs.

RGPs are also an often preferred option for those that have certain conditions such as astigmatism, presbyopia or keratoconus, where soft lenses may not produce the desired visual acuity. RGPs are also a better choice for those who need contact lenses after refractive surgery.

When looking into GP lenses, make sure to first speak to your eye care practitioner to verify if you definitely are a suitable candidate. Who knows…hard lenses could be the right match for you!
